ABSTRACT:
The power supply circuit supplies electric current to a plurality of circuits in turn. The power supply circuit has a power source (5); a resistor (4); one end of which is connected to the power source (5); a first current path (1), one end of which is connected to the other end of the resistor (4), and including a first driver circuit (12); a second current path (2), one end of which is connected to the other end of the resistor (4), and including a second driver circuit (22); and a controller (3) which drives the first and second driver circuits (12, 22) alternatively. The controller (3) controls the on-and-off timings of the first and second driver circuits (12, 22) so that the first current path (12) is maintained in the ON state for a time equal to or more than a predetermined necessary time, and the second current path (22) is broken for a time equal to or less than an allowed time.
